Triphenylphosphine → HCID 19608850, compound

Participants

Reaction Steps

A solution of 2.84 g. (10 mmoles) of the N-benzoyl-5-bromovaleramide prepared above and 3.93 g. (15 mmoles) of triphenylphosphine in 50 ml. of acetonitrile was heated at reflux, under nitrogen, for 72 hours. The acetonitrile was removed by rotary evaporation and the resultant solid was triturated with benzene (3×) then was recrystallized from methylene chloride:ethyl acetate to afford the desired [4-benzoylaminocarbonylbutyl]-triphenylphosphonium bromide weighing 2.38 g. (43.7% yield) melting at 193°-194°.
